My daughter has had difficulty learning to read and she just began Ello two weeks ago and has made tremendous progress in just two weeks! I am so amazed at how well her fluency is picking up in such a short amount of time. We are so grateful for Ello and can tell that a lot of thought and genuine interest was put into the creation of this app to help children who have difficulty with reading. I have never wanted to pay a monthly subscription for any app, until now! It is worth every penny! Thank you, Ello!
